TECHNICAL FIELD OF THE INVENTION

The present invention relates to compounds useful as inhibitors ofprotein kinases. The invention also provides pharmaceutically acceptablecompositions comprising compounds of the present invention and methodsof using said compositions in the treatment of various disorders.

BACKGROUND OF THE INVENTION

The search for new therapeutic agents has been greatly aided in recentyears by a better understanding of the structure of enzymes and otherbiomolecules associated with diseases. One important class of enzymesthat has been the subject of extensive study is protein kinases.

Protein kinases constitute a large family of structurally relatedenzymes that are responsible for the control of a variety of signaltransduction processes within the cell. Protein kinases are thought tohave evolved from a common ancestral gene due to the conservation oftheir structure and catalytic function. Almost all kinases contain asimilar 250-300 amino acid catalytic domain. The kinases may becategorized into families by the substrates they phosphorylate (e.g.,protein-tyrosine, protein-serine/threonine, lipids, etc.).

In general, protein kinases mediate intracellular signaling by effectinga phosphoryl transfer from a nucleoside triphosphate to a proteinacceptor that is involved in a signaling pathway. These phosphorylationevents act as molecular on/off switches that can modulate or regulatethe target protein biological function. These phosphorylation events areultimately triggered in response to a variety of extracellular and otherstimuli. Examples of such stimuli include environmental and chemicalstress signals (e.g., osmotic shock, heat shock, ultraviolet radiation,bacterial endotoxin, and H₂O₂), cytokines (e.g., interleukin-1 (IL-1)and tumor necrosis factor α (TNF-α)), and growth factors (e.g.,granulocyte macrophage-colony-stimulating factor (GM-CSF), andfibroblast growth factor (FGF)). An extracellular stimulus may affectone or more cellular responses related to cell growth, migration,differentiation, secretion of hormones, activation of transcriptionfactors, muscle contraction, glucose metabolism, control of proteinsynthesis, and regulation of the cell cycle.

Many diseases are associated with abnormal cellular responses triggeredby protein kinase-mediated events as described above. These diseasesinclude, but are not limited to, autoimmune diseases, inflammatorydiseases, bone diseases, metabolic diseases, neurological andneurodegenerative diseases, cancer, cardiovascular diseases, allergiesand asthma, Alzheimer's disease, and hormone-related diseases.Accordingly, there remains a need to find protein kinase inhibitorsuseful as therapeutic agents.

As used herein, the term “irreversible” or “irreversible inhibitor”refers to an inhibitor (i.e. a compound) that is able to be covalentlybonded to a target protein kinase in a substantially non-reversiblemanner. That is, whereas a reversible inhibitor is able to bind to (butis generally unable to form a covalent bond) the target protein kinase,and therefore can become dissociated from the target protein kinase, anirreversible inhibitor will remain substantially bound to the targetprotein kinase once covalent bond formation has occurred. Irreversibleinhibitors usually display time dependency, whereby the degree ofinhibition increases with the time with which the inhibitor is incontact with the enzyme. Methods for identifying if a compound is actingas an irreversible inhibitor are known to one of ordinary skill in theart. Such methods include, but are not limited to, enzyme kineticanalysis of the inhibition profile of the compound with the proteinkinase target, the use of mass spectrometry of the protein drug targetmodified in the presence of the inhibitor compound, discontinuousexposure, also known as “washout,” experiments, and the use of labeling,such as radiolabelled inhibitor, to show covalent modification of theenzyme, as well as other methods known to one of skill in the art.

One of ordinary skill in the art will recognize that certain reactivefunctional groups can act as “warheads.” As used herein, the term“warhead” or “warhead group” refers to a functional group present on acompound of the present invention wherein that functional group iscapable of covalently binding to an amino acid residue (such ascysteine, lysine, histidine, or other residues capable of beingcovalently modified) present in the binding pocket of the targetprotein, thereby irreversibly inhibiting the protein. It will beappreciated that the -L-Y group, as defined and described herein,provides such warhead groups for covalently, and irreversibly,inhibiting the protein.

As used herein, the term “inhibitor” is defined as a compound that bindsto and/or inhibits the target protein kinase with measurable affinity.In certain embodiments, an inhibitor has an IC₅₀ and/or binding constantof less about 50 μM, less than about 1 μM, less than about 500 nM, lessthan about 100 nM, or less than about 10 nM.

The terms “measurable affinity” and “measurably inhibit,” as usedherein, means a measurable change in at least one of ErbB1, ErbB2,ErbB3, ErbB4, a TEC-kinase, and/or JAK3 activity between a samplecomprising a compound of the present invention, or composition thereof,and at least one of ErbB1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/orJAK3, and an equivalent sample comprising at least one of ErbB1, ErbB2,ErbB3, ErbB4, a TEC-kinase, and/or JAK3, in the absence of saidcompound, or composition thereof.

Uses of Compounds and Pharmaceutically Acceptable Compositions

Compounds and compositions described herein are generally useful for theinhibition of protein kinase activity of one or more enzymes.

Drug resistance is emerging as a significant challenge for targetedtherapies. For example, drug resistance has been reported for Gleevec®and Iressa®, as well as several other kinase inhibitors in development.In addition, drug resistance has been reported for the cKit and PDGFRreceptors. It has been reported that irreversible inhibitors may beeffective against drug resistant forms of protein kinases (Kwak, E. L.,R. Sordella, et al. (2005). “Irreversible inhibitors of the EGF receptormay circumvent acquired resistance to gefitinib.” PNAS 102(21):7665-7670.) Without wishing to be bound by any particular theory, it isbelieved that compounds of the present invention may be effectiveinhibitors of drug resistant forms of protein kinases.

As used herein, the term “clinical drug resistance” refers to the lossof susceptibility of a drug target to drug treatment as a consequence ofmutations in the drug target.

As used herein, the term “resistance” refers to changes in the wild-typenucleic acid sequence coding a target protein, and/or the proteinsequence of the target, which changes decrease or abolish the inhibitoryeffect of the inhibitor on the target protein.

Examples of kinases that are inhibited by the compounds and compositionsdescribed herein and against which the methods described herein areuseful include ErbB1, ErbB2, ErbB3, ErbB4, a TEC-kinase (including BTK,ITK, TEC, BMX and RLK), and/or JAK3, or a mutant thereof.

The activity of a compound utilized in this invention as an inhibitor ofErbB1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutantthereof, may be assayed in vitro, in vivo or in a cell line. In vitroassays include assays that determine inhibition of either thephosphorylation activity and/or the subsequent functional consequences,or ATPase activity of activated ErbB1, ErbB2, ErbB3, ErbB4, aTEC-kinase, and/or JAK3, or a mutant thereof. Alternate in vitro assaysquantitate the ability of the inhibitor to bind to ErbB1, ErbB2, ErbB3,ErbB4, a TEC-kinase, and/or JAK3. Inhibitor binding may be measured byradiolabeling the inhibitor prior to binding, isolating theinhibitor/ErbB1, inhibitor/ErbB2, inhibitor/ErbB3, inhibitor/ErbB4,inhibitor/TEC-kinase (i.e., TEC, BTK, ITK, RLK and BMX), orinhibitor/JAK3 complex and determining the amount of radiolabel bound.Alternatively, inhibitor binding may be determined by running acompetition experiment where new inhibitors are incubated with ErbB1,ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3 bound to knownradioligands. Detailed conditions for assaying a compound utilized inthis invention as an inhibitor of ErbB1, ErbB2, ErbB3, ErbB4, aTEC-kinase, and/or JAK3, or a mutant thereof, are set forth in theExamples below.

Protein tyrosine kinases are a class of enzymes that catalyze thetransfer of a phosphate group from ATP or GTP to a tyrosine residuelocated on a protein substrate. Receptor tyrosine kinases act totransmit signals from the outside of a cell to the inside by activatingsecondary messaging effectors via a phosphorylation event. A variety ofcellular processes are promoted by these signals, includingproliferation, carbohydrate utilization, protein synthesis,angiogenesis, cell growth, and cell survival.

(a) ErbB Family

ErbB receptors, a major family of receptor tyrosine kinases, arecomposed of an extracellular ligand binding domain, a singletransmembrane domain, and an intracellular domain with tyrosine kinaseactivity. The ErbB family comprises ErbB1 (commonly known as EGFR),ErbB2 (commonly known as HER2 or neu), ErbB3 (commonly known as HER3),and ErbB4 (commonly known as HER4). More than 10 ligands (including EGF,TGFα, AR, BTC, EPR, HB-EGF, NRG-1, NRG-2, NRG-3, NRG-4) have beenidentified for the various receptor family members. Upon ligand bindingthe extracellular domain undergoes conformational change, allowing theformation of homodimers or heterodimers with other members of the ErbBfamily. Dimerization induces tyrosine phosphorylation of specificresidues in the intracellular domain that serve as docking sites foradaptor proteins and downstream effectors. In some contexts, activationof phosphatidyl-inositol 3-kinase (PI3K) and mitogen-activated proteinkinase pathways occur, leading to cell proliferation and survival (Lin,N. U.; Winer, E. P., Breast Cancer Res 6: 204-210, 2004).

Interaction between family members is necessitated by deficiencies inErbB2, which has no known ligand, and ErbB3, which is kinase dead. EGFR,ErbB3, and ErbB4 bind ligand to induce ErbB receptor homodimerization orheterodimerization, whereas ErbB2 functions as the preferreddimerization partner. The composition of the pairwise combinations isimportant for signal diversification, as dimer identity determines whichdownstream pathways are activated. Representative downstream geneproducts in the ErbB signal transduction pathway include Shc, Grb2,SOS1, Ras, Raf1, Mek, ERK1, ERK2, ERα, Akt, mTOR, FKHR, p27, Cyclin D1,FasL, GSK-3, Bad, and STAT3.

There is strong precedent for involvement of the EGFR and other membersof the ErbB family in human cancer because over 60% of all solid tumorsoverexpress at least one of these proteins or their ligands.Constitutively active, tumorigenic EGFR vIII, a mutant possessing atruncated extracellular domain, has been reported to be present in up to78% of breast carcinomas and has also been found in glioblastomas.Overexpression of EGFR is commonly found in breast, lung, head and neck,bladder tumors, while ErbB2 expression is frequently elevated in humantumors of epithelial origin. Activating mutations in the tyrosine kinasedomain have been identified in patients with non-small cell lung cancer(Lin, N. U.; Winer, E. P., Breast Cancer Res 6: 204-210, 2004). ErbB1and/or ErbB2 amplification has also been implicated in squamous cellcarcinomas, salivary gland carcinomas, ovarian carcinomas, andpancreatic cancers (Cooper, G. C. Oncogenes. 2^(nd) ed. Sudbury: Jonesand Barlett, 1995; Zhang, Y., et al., Cancer Res 66: 1025-32, 2006).Overexpression of ErbB2 has potent transforming activity, likely due toits ability to cooperate with other ErbB receptors (Sherman, L., et al.,Oncogene 18: 6692-99, 1999). In fact, some human cancers thatoverexpress both EGFR and ErbB2 have a poorer prognosis than cancersthat overexpress either receptor alone.

The ErbB signaling network is often a key component in the pathogenesisof breast cancer. Amplification of ErbB2 is associated with anaggressive tumor phenotype that is characterized by relatively rapidtumor growth, metastatic spread to visceral sites, and drug resistance.ErbB2 has been shown to be amplified in 20% of axillary node-negative(“ANN”) breast cancer cases, and this amplification has been identifiedas an independent prognostic factor for risk of recurrence in ANN breastcancer. (Andrulis, I. L., et al., J Clin Oncol 16: 1340-9, 1998).

Targeted blockade of ErbB signaling with trastuzumab (Herceptin), amonoclonal antibody directed at ErbB2, has been shown to improvesurvival in women with ErbB2-positive, advanced breast cancer. Othermonoclonal antibodies directed against ErbB receptors include cetuximab(Erbitux) and panitumumab (Vectibix).

Several small molecule tyrosine kinase inhibitors (TKIs) have been foundto act selectively upon ErbB family members. Notable examples includegefitinib (Iressa) and erlotinib (Tarceva), both of which target theEGFR. These small molecules compete with ATP for binding to the kinasedomain of the receptor. Compared to monoclonal antibodies, TKIs haveseveral advantages in that they are orally bioavailable, well-tolerated,and appear to be active against truncated forms of ErbB2 and EGFRreceptors (e.g., EGFR vIII) in vitro. In addition, the small size ofsmall molecule TKIs may allow them to penetrate sanctuary sites such asthe central nervous system. Finally, the homology between kinase domainsof ErbB receptors allows for development of TKIs that target more thanone member of the ErbB family simultaneously, the advantages of whichare described herein.

Although certain malignancies have been linked to the overexpression ofindividual receptors, efficient signal transduction relies on thecoexpression of ErbB receptor family members. This cooperation of ErbBreceptor family members in signal transduction and malignanttransformation may limit the success of agents that target individualreceptors in the treatment of cancer; a potential mechanism ofresistance to agents targeting a single ErbB receptor is upregulation ofother members of the receptor family (Britten, C. D., Mol Cancer Ther 3:1335-42, 2004).

Agents that target two or more ErbB receptors are called pan-ErbBregulators. ERRP is a pan-ErbB negative regulator that is expressed inmost benign pancreatic ductal epithelium and islet cells. Tumors havebeen found to experience a progressive loss in ERRP expression. ThatErbitux and Herceptin show success in a limited patient base (tumorshaving increased expression of EGFR or ErbB2) could be partly due tocoexpression of multiple ErbB family members.

In both in vitro and in vivo models, strategies that employ a dual ErbBapproach seem to have greater antitumor activity than agents targeting asingle ErbB receptor. Thus, agents that target multiple members of ErbBfamily are likely to provide therapeutic benefit to a broader patientpopulation (Zhang, Y., et al., Cancer Res 66: 1025-32, 2006). In certainembodiments, provided compounds inhibit one or more of ErbB1, ErbB2,ErbB3, and ErbB4. In some embodiments, provided compounds inhibit two ormore of ErbB1, ErbB2, ErbB3, and ErbB4, or a mutant thereof, and aretherefore pan-ErbB inhibitors.

Clearly, there is growing evidence to support the concurrent inhibitionof two or more ErbB (i.e., pan-ErbB) receptors in cancer therapy.Possible pan-ErbB approaches with small molecules include usingcombinations of agents that target individual ErbB receptors, usingsingle agents that target multiple ErbB receptors, or using agents thatinterfere with ErbB receptor interactions (e.g., dimerization).Additional strategies include therapies utilizing a small molecule incombination with antibodies, or chemoprevention therapies (Lin, N. U.;Winer, E. P., Breast Cancer Res 6: 204-210, 2004).

An example of small molecule pan-ErbB inhibition is CI-1033, anirreversible pan-ErbB inhibitor that covalently binds to the ATP bindingsite of the intracellular kinase domain. Another irreversible pan-ErbBreceptor tyrosine kinase inhibitor is HKI-272, which inhibits the growthof tumor cells that express ErbB-1 (EGFR) and ErbB-2 (HER-2) in cultureand xenografts, and has antitumor activity in HER-2-positive breastcancer (Andrulis, I. L., et al., J Clin Oncol 16: 1340-9, 1998).Irreversible inhibitors have demonstrated superior antitumor activity incomparison with reversible inhibitors.

Neurofibromatosis type I (NF1) is a dominantly inherited human diseaseaffecting one in 2500-3500 individuals. Several organ systems areaffected, including bones, skin, iris, and the central nervous system,as manifested in learning disabilities and gliomas. A hallmark of NF1 isthe development of benign tumors of the peripheral nervous system(neurofibromas), which vary greatly in both number and size amongpatients. Neurofibromas are heterogeneous tumors composed of Schwanncells, neurons, fibroblasts and other cells, w/Schwann cells being themajor (60-80%) cell type.

Abberant expression of the EGFR is associated with tumor development inNF1 and in animal models of NF1, suggesting a role in pathogenesis andrepresenting a novel potential therapeutic target. EGFR expressionaffects the growth of tumor cell lines derived from NF1 patients underconditions where EGF is not the primary factor driving growth of thecells. These data suggest that EGFR may play an important role in NF1tumorigenesis and Schwann cell transformation (DeClue, J. E., et al., JClin Invest 105: 1233-41, 2000).

Patients with NF1 develop aggressive Schwann cell neoplasmas known asmalignant peripheral nerve sheath tumors (MPNSTs). Schwann cells are themajor supportive cell population in the peripheral nervous system.Neoplastic Schwann cells within these neoplasms variably express theErbB tyrosine kinases mediating NRG-1 responses (ErbB2, ErbB3, ErbB4).Neuregulin-1 (NRG-1) proteins promote the differentiation, survival,and/or proliferation of many cell types in the developing nervoussystem, and overexpression of NRG-1 in myelinating Schwann cells inducesthe formation of malignant peripheral nerve sheath tumors (MPNSTs)(Fallon, K. B., et al., J Neuro Oncol 66: 273-84, 2004).

Deregulation of Schwann cell growth is a primary defect driving thedevelopment of both benign neurofibromas and MPNST in neurofibromatosistype I (NF1) patients. Growth of MPNSTs and transformed mouse Schwanncells in vitro is highly EGF-dependent and can be blocked by EGFRinhibitors under conditions where EGF is the primary growth factor. Somehuman MPNST cell lines have been found to demonstrate constitutive ErbBphosphorylation. While treatment with ErbB inhibitors abolishes ErbBphosphorylation and reduces DNA synthesis in these lines, effectivechemotherapeutic regimens for MPNST remain elusive (Stonecypher, M. S.,et al., Oncogene 24: 5589-5605, 2005).

Schwannomas are peripheral nerve tumors comprised almost entirely ofSchwann-like cells, and typically have mutations in theneurofibromatosis type II (NF2) tumor suppressor gene. Ninety percent ofNF2 patients develop bilateral vestibular schwannomas and/or spinalschwannomas. Enlarging schwannomas can compress adjacent structures,resulting in deafness and other neurologic problems. Surgical removal ofthese tumors is difficult, often resulting in increased patientmorbidity.

Both normal human Schwann cells and schwannoma cells express neuregulinreceptors (i.e., ErbB receptors), and schwannoma cells proliferate inresponse to neuregulin. It is possible that aberrant neuregulinproduction or response contributes to aberrant schwannoma cellproliferation (Pelton, P. D., et al., Oncogene 17: 2195-2209, 1998).

The NF2 tumor suppressor, Merlin, is a membrane/cytoskeleton-associatedprotein implicated in the regulation of tyrosine kinase activity.Genetic interactions between a Merlin mutation and EGFR pathwaymutations have been documented in Drosophila (LaJeunesse, D. R., et al.,Genetics 158: 667-79, 2001). Other evidence suggests Merlin can inhibitEGFR internalization and signaling upon cell-cell contact by restrainingthe EGFR into a membrane compartment from which it can neither signalnor be internalized (McClatchey, A. I., et al., Genes and Development19: 2265-77, 2005; Curto, M. C., et al., J Cell Biol 177: 893-903,2007).

As used herein, the terms “treatment,” “treat,” and “treating” refer toreversing, alleviating, delaying the onset of, or inhibiting theprogress of a disease or disorder, or one or more symptoms thereof, asdescribed herein. In some embodiments, treatment may be administeredafter one or more symptoms have developed. In other embodiments,treatment may be administered in the absence of symptoms. For example,treatment may be administered to a susceptible individual prior to theonset of symptoms (e.g., in light of a history of symptoms and/or inlight of genetic or other susceptibility factors). Treatment may also becontinued after symptoms have resolved, for example to prevent or delaytheir recurrence.

Provided compounds are inhibitors of one or more of ErbB1, ErbB2, ErbB3,and ErbB4 and are therefore useful for treating one or more disordersassociated with activity of one of more of ErbB1, ErbB2, ErbB3, andErbB4.

(b) TEC Family

The TEC family of non-receptor tyrosine kinases, referred to herein as“TEC-kinases,” plays a central role in signaling throughantigen-receptors such as the TCR, BCR and Fc receptors (reviewed inMiller A, et al. Current Opinion in Immunology 14; 331-340 (2002).TEC-kinases are essential for T cell activation. Three members of thefamily, Itk, Rlk and, are activated downstream of antigen receptorengagement in T cells and transmit signals to downstream effectors,including PLC-γ. Combined deletion of Itk and Rlk in mice leads to aprofound inhibition of TCR responses including proliferation, cytokineproduction and immune responses to an intracellular parasite (Toxoplasmagondii) (Schaeffer et al., Science 284; 638-641 (1999)). Intracellularsignalling following TCR engagement is effected in ITK/RLK deficient Tcells; inositol triphosphate production, calcium mobilization and MAPkinase activation are all reduced. Tec-kinases are also essential for Bcell development and activation.

TEC-kinases include five family members, which are expressed primarilyin hematopoietic cells: TEC, BTK, ITK (also known as TSK and EMT), RLK(also known as TXK), and BMX (also known as ETK). Additional relatedTEC-kinases have been found in Drosophila melanogaster, zebrafish (Daniorerió), skate (Raja eglanteria), and sea urchin (Anthocidariscrassispina).

(c) Bruton's Tyrosine Kinase (BTK)

Bruton's tyrosine kinase (“BTK”), a member of TEC-kinases, is a keysignaling enzyme expressed in all hematopoietic cell types except Tlymphocytes and natural killer cells. BTK plays an essential role in theB-cell signaling pathway linking cell surface B-cell receptor (BCR)stimulation to downstream intracellular responses.

BTK is a key regulator of B-cell development, activation, signaling, andsurvival (Kurosaki, Curr Op Imm, 2000, 276-281; Schaeffer andSchwartzberg, Curr Op Imm 2000, 282-288). In addition, BTK plays a rolein a number of other hematopoietic cell signaling pathways, e.g., Tolllike receptor (TLR) and cytokine receptor-mediated TNF-α production inmacrophages, IgE receptor (Fc_epsilon_RI) signaling in mast cells,inhibition of Fas/APO-1 apoptotic signaling in B-lineage lymphoid cells,and collagen-stimulated platelet aggregation. See, e.g., C. A. Jeffries,et al., (2003), Journal of Biological Chemistry 278:26258-26264; N. J.Horwood, et al., (2003), The Journal of Experimental Medicine 197:1603-1611; Iwaki et al. (2005), Journal of Biological Chemistry280(48):40261-40270; Vassilev et al. (1999), Journal of BiologicalChemistry 274(3): 1646-1656, and Quek et al. (1998), Current Biology8(20): 1137-1140.

Patients with mutations in BTK have a profound block in B celldevelopment, resulting in the almost complete absence of mature Blymphocytes and plasma cells, severely reduced Ig levels and a profoundinhibition of humoral response to recall antigens (reviewed in Vihinenet al Frontiers in Bioscience 5: d917-928). Mice deficient in BTK alsohave a reduced number of peripheral B cells and greatly decreased serumlevels of IgM and IgG3. BTK deletion in mice has a profound effect on Bcell proliferation induced by anti-IgM, and inhibits immune responses tothymus-independent type II antigens (Ellmeier et al, J Exp Med 192:1611-1623 (2000)). BTK also plays a crucial role in mast cell activationthrough the high-affinity IgE receptor (Fc_epsilon_RI). BTK deficientmurine mast cells have reduced degranulation and decreased production ofproinflammatory cytokines following Fc_epsilon_RI cross-linking(Kawakami et al. Journal of Leukocyte Biology 65: 286-290).

Provided compounds are inhibitors of BTK and are therefore useful fortreating one or more disorders associated with activity of BTK. Thus, insome embodiments, the present invention provides a method for treating aBTK-mediated disorder comprising the step of administering to a patientin need thereof a compound of the present invention, or pharmaceuticallyacceptable composition thereof.

(d) ITK

Interleukin-2 inducible T-cell kinase (“ITK”) is expressed in T cells,mast cells and natural killer cells. It is activated in T cells uponstimulation of the T cell receptor (TCR), and in mast cells uponactivation of the high affinity IgE receptor. Following receptorstimulation in T cells, Lck, a Src tyrosine kinase family member,phosphorylates Y511 in the kinase domain activation loop of ITK (S. D.Heyeck et al., 1997, J. Biol. Chem, 272, 25401-25408). Activated ITK,together with Zap-70 is required for phosphorylation and activation ofPLC-gamma (S. C. Bunnell et al., 2000, J. Biol. Chem., 275, 2219-2230).PLC-gamma catalyzes the formation of inositol 1,4,5-triphosphate anddiacylglycerol, leading to calcium mobilization and PKC activation,respectively. These events activate numerous downstream pathways andlead ultimately to degranulation (mast cells) and cytokine geneexpression (T cells) (Y. Kawakami et al., 1999, J. Leukocyte Biol., 65,286-290).

The role of ITK in T cell activation has been confirmed in ITK knockoutmice. CD4⁺ T cells from ITK knockout mice have a diminishedproliferative response in a mixed lymphocyte reaction or upon Con A oranti-CD3 stimulation. (X. C. Liao and D. R. Littman, 1995, Immunity, 3,757-769). Also, T cells from ITK knockout mice produced little IL-2 uponTCR stimulation resulting in reduced proliferation of these cells. Inanother study, ITK deficient CD4⁺ T cells produced reduced levels ofcytokines including IL-4, IL-5 and IL-13 upon stimulation of the TCR,even after priming with inducing conditions (D. J. Fowell, 1999,Immunity, 11, 399-409).

The role of ITK in PLC-gamma activation and in calcium mobilization wasalso confirmed in the T cells of these knockout mice, which had severelyimpaired IP₃ generation and no extracellular calcium influx upon TCRstimulation (K. Liu et al., 1998, J. Exp. Med. 187, 1721-1727). Suchstudies support a key role for ITK in activation of T cells and mastcells. Thus an inhibitor of ITK would be of therapeutic benefit indiseases mediated by inappropriate activation of these cells.

It has been well established that T cells play an important role inregulating the immune response (Powrie and Coffman, 1993, ImmunologyToday, 14, 270-274). Indeed, activation of T cells is often theinitiating event in immunological disorders. Following activation of theTCR, there is an influx of calcium that is required for T cellactivation. Upon activation, T cells produce cytokines, including IL-2,4, 5, 9, 10, and 13 leading to T cell proliferation, differentiation,and effector function. Clinical studies with inhibitors of IL-2 haveshown that interference with T cell activation and proliferationeffectively suppresses immune response in vivo (Waldmann, 1993,Immunology Today, 14, 264-270). Accordingly, agents that inhibit Tlymphocyte activation and subsequent cytokine production, aretherapeutically useful for selectively suppressing the immune responsein a patient in need of such immunosuppression.

Mast cells play a critical roll in asthma and allergic disorders byreleasing pro-inflammatory mediators and cytokines Antigen-mediatedaggregation of Fc.epsilon.RI, the high-affinity receptor for IgE,results in activation of mast cells (D. B. Corry et al., 1999, Nature,402, B18-23). This triggers a series of signaling events resulting inthe release of mediators, including histamine, proteases, leukotrienesand cytokines (J. R. Gordon et al., 1990, Immunology Today, 11,458-464.) These mediators cause increased vascular permeability, mucusproduction, bronchoconstriction, tissue degradation and inflammationthus playing key roles in the etiology and symptoms of asthma andallergic disorders.

Published data using ITK knockout mice suggests that in the absence ofITK function, increased numbers of memory T cells are generated (A. T.Miller et al., 2002 The Journal of Immunology, 168, 2163-2172). Onestrategy to improve vaccination methods is to increase the number ofmemory T cells generated (S. M. Kaech et al., Nature Reviews Immunology,2, 251-262). In addition, deletion of ITK in mice results in reduced Tcell receptor (TCR)-induced proliferation and secretion of the cytokinesIL-2, IL-4, IL-5, IL-10 and IFN-γ (Schaeffer et al, Science 284; 638-641(1999)), Fowell et al, Immunity 11, 399-409 (1999), Schaeffer et al,Nature Immunology 2 (12): 1183-1188 (2001))). The immunological symptomsof allergic asthma are attenuated in ITK−/−mice. Lung inflammation,eosinophil infiltration and mucus production are drastically reduced inITK−/−mice in response to challenge with the allergen OVA (Mueller etal, Journal of Immunology 170: 5056-5063 (2003)). ITK has also beenimplicated in atopic dermatitis. This gene has been reported to be morehighly expressed in peripheral blood T cells from patients with moderateand/or severe atopic dermatitis than in controls or patients with mildatopic dermatitis (Matsumoto et al, International Archives of Allergyand Immunology 129: 327-340 (2002)).

Splenocytes from RLK−/−mice secrete half the IL-2 produced by wild typeanimals in response to TCR engagement (Schaeffer et al, Science 284:638-641 (1999)), while combined deletion of ITK and RLK in mice leads toa profound inhibition of TCR-induced responses including proliferationand production of the cytokines IL-2, IL-4, IL-5 and IFN-γ (Schaeffer etal, Nature Immunology 2 (12): 1183-1188 (2001), Schaeffer et al, Science284: 638-641 (1999)). Intracellular signalling following TCR engagementis effected in ITK/RLK deficient T cells; inositol triphosphateproduction, calcium mobilization, MAP kinase activation, and activationof the transcription factors NFAT and AP-1 are all reduced (Schaeffer etal, Science 284: 638-641 (1999), Schaeffer et al, Nature Immunology 2(12): 1183-1188 (2001)).

Provided compounds are inhibitors of ITK and are therefore useful fortreating one or more disorders associated with activity of ITK. Thus, insome embodiments, the present invention provides a method for treatingan ITK-mediated disorder comprising the step of administering to apatient in need thereof a compound of the present invention, orpharmaceutically acceptable composition thereof.

As used herein, the term “ITK-mediated” disorders or conditions as usedherein means any disease or other deleterious condition in which ITK, ora mutant thereof, is known to play a role. Accordingly, anotherembodiment of the present invention relates to treating or lessening theseverity of one or more diseases in which ITK, or a mutant thereof, isknown to play a role. Specifically, the present invention relates to amethod of treating or lessening the severity of a disease or conditionselected from a mast cell-mediated condition, a basophil-mediateddisorder, an immune or allergic disorder, wherein said method comprisesadministering to a patient in need thereof a compound or compositionaccording to the present invention.

In some embodiments, the present invention provides a method fortreating or lessening the severity of one or more diseases andconditions associated with ITK, wherein the disease or condition is animmune disorder, including inflammatory diseases, autoimmune diseases,organ and bone marrow transplant rejection and other disordersassociated with T cell-mediated immune response or mast cell-mediatedimmune response.

In certain embodiments, the present invention provides a method fortreating or lessening the severity of one or more diseases andconditions associated with ITK, wherein the disease or condition is amast cell driven conditions, a basophil-mediated disorder, reversibleobstructive airway disease, asthma, rhinitis, chronic obstructivepulmonary disease (COPD), peripheral T-cell lymphomas or HIV [also knownas Acquired Immunodeficiency Syndrome (AIDS)]. Such conditions includethose described in Readinger, et al., PNAS 105: 6684-6689 (2008).

(e) JAK Family

The Janus kinases (JAK) are a family of tyrosine kinases consisting ofJAK1, JAK2, JAK3 and TYK2. The JAKs play a critical role in cytokinesignaling. The down-stream substrates of the JAK family of kinasesinclude the signal transducer and activator of transcription (STAT)proteins. JAK/STAT signaling has been implicated in the mediation ofmany abnormal immune responses such as allergies, asthma, autoimmunediseases such as transplant rejection, rheumatoid arthritis, amyotrophiclateral sclerosis and multiple sclerosis as well as in solid andhematologic malignancies such as leukemias and lymphomas. Thepharmaceutical intervention in the JAK/STAT pathway has been reviewed[Frank, Mol. Med. 5: 432-456 (1999) & Seidel, et al, Oncogene 19:2645-2656 (2000)].

JAK1, JAK2, and TYK2 are ubiquitously expressed, while JAK3 ispredominantly expressed in hematopoietic cells. JAK3 binds exclusivelyto the common cytokine receptor gamma chain (yc) and is activated byIL-2, IL-4, IL-7, IL-9, and IL-15.

The proliferation and survival of murine mast cells induced by IL-4 andIL-9 have, in fact, been shown to be dependent on JAK3- and yc-signaling[Suzuki et al, Blood 96: 2172-2180 (2000)].

Cross-linking of the high-affinity immunoglobulin (Ig) E receptors ofsensitized mast cells leads to a release of proinflammatory mediators,including a number of vasoactive cytokines resulting in acute allergic,or immediate (type I) hypersensitivity reactions [Gordon et al, Nature346: 274-276 (1990) & Galli, N. Engl. J. Med., 328: 257-265 (1993)]. Acrucial role for JAK3 in IgE receptor-mediated mast cell responses invitro and in vivo has been established [Malaviya, et al, Biochem.Biophys. Res. Commun. 257: 807-813 (1999)]. In addition, the preventionof type I hypersensitivity reactions, including anaphylaxis, mediated bymast cell-activation through inhibition of JAK3 has also been reported[Malaviya et al, J. Biol. Chem. 274: 27028-27038 (1999)]. Targeting mastcells with JAK3 inhibitors modulated mast cell degranulation in vitroand prevented IgE receptor/antigen-mediated anaphylactic reactions invivo.

A recent study described the successful targeting of JAK3 for immunesuppression and allograft acceptance. The study demonstrated adose-dependent survival of buffalo heart allograft in Wistar Furthrecipients upon administration of inhibitors of JAK3 indicating thepossibility of regulating unwanted immune responses in graft versus hostdisease [Kirken, Transpl. Proc. 33: 3268-3270 (2001)].

IL-4-mediated STAT-phosphorylation has been implicated as the mechanisminvolved in early and late stages of rheumatoid arthritis (RA).Up-regulation of proinflammatory cytokines in RA synovium and synovialfluid is a characteristic of the disease. It has been demostrated thatIL-4-mediated activation of IL-4/STAT pathway is mediated through theJanus kinases (JAK 1 & 3) and that IL-4-associated JAK kinases areexpressed in the RA synovium [Muller-Ladner, et al, J. Immunol. 164:3894-3901 (2000)].

Familial amyotrophic lateral sclerosis (FALS) is a fatalneurodegenerative disorder affecting about 10% of ALS patients. Thesurvival rates of FALS mice were increased upon treatment with a JAK3specific inhibitor. This confirmed that JAK3 plays a role in FALS[Trieu, et al, Biochem. Biophys. Res. Commun. 267: 22-25 (2000)].

Signal transducer and activator of transcription (STAT) proteins areactivated by, among others, the JAK family kinases. Results form arecent study suggested the possibility of intervention in the JAK/STATsignaling pathway by targeting JAK family kinases with specificinhibitors for the treatment of leukemia [Sudbeck, et al., Clin. CancerRes. 5: 1569-1582 (1999)]. JAK3 specific compounds were shown to inhibitthe clonogenic growth of JAK3-expressing cell lines DAUDI, RAMOS, LC1;19, NALM-6, MOLT-3 and HL-60. Inhibition of JAK3 and TYK 2 abrogatedtyrosine phosphorylation of STAT3, and inhibited cell growth of mycosisfungoides, a form of cutaneous T cell lymphoma.

According to another embodiment, the invention provides a method fortreating or lessening the severity of a JAK3-mediated disease orcondition in a patient comprising the step of administering to saidpatient a composition according to the present invention.

Accordingly, another embodiment of the present invention relatesto treating or lessening the severity of one or more diseases in whichJAK3 is known to play a role. Specifically, the present inventionrelates to a method of treating or lessening the severity of a diseaseor condition selected from immune responses such as allergic or type Ihypersensitivity reactions, asthma, autoimmune diseases such astransplant rejection, graft versus host disease, rheumatoid arthritis,amyotrophic lateral sclerosis, and multiple sclerosis, neurodegenerativedisorders such as familial amyotrophic lateral sclerosis (FALS), as wellas in solid and hematologic malignancies such as leukemias andlymphomas, wherein said method comprises administering to a patient inneed thereof a composition according to the present invention.

Compounds of the invention arepreferably formulated in dosage unit form for ease of administration anduniformity of dosage. The expression “dosage unit form” as used hereinrefers to a physically discrete unit of agent appropriate for thepatient to be treated. It will be understood, however, that the totaldaily usage of the compounds and compositions of the present inventionwill be decided by the attending physician within the scope of soundmedical judgment. The specific effective dose level for any particularpatient or organism will depend upon a variety of factors including thedisorder being treated and the severity of the disorder; the activity ofthe specific compound employed; the specific composition employed; theage, body weight, general health, sex and diet of the patient; the timeof administration, route of administration, and rate of excretion of thespecific compound employed; the duration of the treatment; drugs used incombination or coincidental with the specific compound employed, andlike factors well known in the medical arts. The term “patient”, as usedherein, means an animal, preferably a mammal, and most preferably ahuman.

Pharmaceutically acceptable compositions of this invention can beadministered to humans and other animals orally, rectally, parenterally,intracisternally, intravaginally, intraperitoneally, topically (as bypowders, ointments, or drops), bucally, as an oral or nasal spray, orthe like, depending on the severity of the infection being treated. Incertain embodiments, the compounds of the invention may be administeredorally or parenterally at dosage levels of about 0.01 mg/kg to about 50mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subjectbody weight per day, one or more times a day, to obtain the desiredtherapeutic effect.

Liquid dosage forms for oral administration include, but are not limitedto, pharmaceutically acceptable emulsions, microemulsions, solutions,suspensions, syrups and elixirs. In addition to the active compounds,the liquid dosage forms may contain inert diluents commonly used in theart such as, for example, water or other solvents, solubilizing agentsand emulsifiers such as ethyl alcohol, isopropyl alcohol, ethylcarbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propyleneglycol, 1,3-butylene glycol, dimethylformamide, oils (in particular,cottonseed, groundnut, corn, germ, olive, castor, and sesame oils),glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fattyacid esters of sorbitan, and mixtures thereof. Besides inert diluents,the oral compositions can also include adjuvants such as wetting agents,emulsifying and suspending agents, sweetening, flavoring, and perfumingagents.

Injectable preparations, for example, sterile injectable aqueous oroleaginous suspensions may be formulated according to the known artusing suitable dispersing or wetting agents and suspending agents. Thesterile injectable preparation may also be a sterile injectablesolution, suspension or emulsion in a nontoxic parenterally acceptablediluent or solvent, for example, as a solution in 1,3-butanediol. Amongthe acceptable vehicles and solvents that may be employed are water,Ringer's solution, U.S.P. and isotonic sodium chloride solution. Inaddition, sterile, fixed oils are conventionally employed as a solventor suspending medium. For this purpose any bland fixed oil can beemployed including synthetic mono- or diglycerides. In addition, fattyacids such as oleic acid are used in the preparation of injectables.

Injectable formulations can be sterilized, for example, by filtrationthrough a bacterial-retaining filter, or by incorporating sterilizingagents in the form of sterile solid compositions which can be dissolvedor dispersed in sterile water or other sterile injectable medium priorto use.

In order to prolong the effect of a compound of the present invention,it is often desirable to slow the absorption of the compound fromsubcutaneous or intramuscular injection. This may be accomplished by theuse of a liquid suspension of crystalline or amorphous material withpoor water solubility. The rate of absorption of the compound thendepends upon its rate of dissolution that, in turn, may depend uponcrystal size and crystalline form. Alternatively, delayed absorption ofa parenterally administered compound form is accomplished by dissolvingor suspending the compound in an oil vehicle. Injectable depot forms aremade by forming microencapsule matrices of the compound in biodegradablepolymers such as polylactide-polyglycolide. Depending upon the ratio ofcompound to polymer and the nature of the particular polymer employed,the rate of compound release can be controlled. Examples of otherbiodegradable polymers include poly(orthoesters) and poly(anhydrides).Depot injectable formulations are also prepared by entrapping thecompound in liposomes or microemulsions that are compatible with bodytissues.

Compositions for rectal or vaginal administration are preferablysuppositories which can be prepared by mixing the compounds of thisinvention with suitable non-irritating excipients or carriers such ascocoa butter, polyethylene glycol or a suppository wax which are solidat ambient temperature but liquid at body temperature and therefore meltin the rectum or vaginal cavity and release the active compound.

In such solid dosage forms, the activecompound is mixed with at least one inert, pharmaceutically acceptableexcipient or carrier such as sodium citrate or dicalcium phosphateand/or a) fillers or extenders such as starches, lactose, sucrose,glucose, mannitol, and silicic acid, b) binders such as, for example,carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone,sucrose, and acacia, c) humectants such as glycerol, d) disintegratingagents such as agar-agar, calcium carbonate, potato or tapioca starch,alginic acid, certain silicates, and sodium carbonate, e) solutionretarding agents such as paraffin, f) absorption accelerators such asquaternary ammonium compounds, g) wetting agents such as, for example,cetyl alcohol and glycerol monostearate, h) absorbents such as kaolinand bentonite clay, and i) lubricants such as talc, calcium stearate,magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate,and mixtures thereof. In the case of capsules, tablets and pills, thedosage form may also comprise buffering agents.

Solid compositions of a similar type may also be employed as fillers insoft and hard-filled gelatin capsules using such excipients as lactoseor milk sugar as well as high molecular weight polyethylene glycols andthe like. The solid dosage forms of tablets, dragees, capsules, pills,and granules can be prepared with coatings and shells such as entericcoatings and other coatings well known in the pharmaceutical formulatingart. They may optionally contain opacifying agents and can also be of acomposition that they release the active ingredient(s) only, orpreferentially, in a certain part of the intestinal tract, optionally,in a delayed manner. Examples of embedding compositions that can be usedinclude polymeric substances and waxes. Solid compositions of a similartype may also be employed as fillers in soft and hard-filled gelatincapsules using such excipients as lactose or milk sugar as well as highmolecular weight polethylene glycols and the like.

The active compounds can also be in micro-encapsulated form with one ormore excipients as noted above. The solid dosage forms of tablets,dragees, capsules, pills, and granules can be prepared with coatings andshells such as enteric coatings, release controlling coatings and othercoatings well known in the pharmaceutical formulating art. In such soliddosage forms the active compound may be admixed with at least one inertdiluent such as sucrose, lactose or starch. Such dosage forms may alsocomprise, as is normal practice, additional substances other than inertdiluents, e.g., tableting lubricants and other tableting aids such amagnesium stearate and microcrystalline cellulose. In the case ofcapsules, tablets and pills, the dosage forms may also comprisebuffering agents. They may optionally contain opacifying agents and canalso be of a composition that they release the active ingredient(s)only, or preferentially, in a certain part of the intestinal tract,optionally, in a delayed manner. Examples of embedding compositions thatcan be used include polymeric substances and waxes.

In some embodiments, such probe compounds of the present inventioncomprise a provided compound of formula I-a or I-b tethered to adetectable moiety, Rt, by a bivalent tethering moiety, -T-. Thetethering moiety may be attached to a compound of formula I-a or I-b viaRing A, Ring B, or R¹. One of ordinary skill in the art will appreciatethat when a tethering moiety is attached to R¹, R¹ is a bivalent warheadgroup denoted as R^(1′). In certain embodiments, a provided probecompound is selected from any of formula V-a, V-b, VI-a, VI-b, VII-a, orVII-b:

Example 256 Human Primary B Cell Proliferation Assay

Human naïve B cells were purified from 100 mL whole blood using a MACSpurification kit designed to isolate CD19+, IgD+ cells by negativeselection. Purified naïve B cells were resuspended in RPMI complete andstimulated with 5 μg/ml α-IgM for 72 hours. ³H-Thymidine was included inthe culture media for the final 16 h, cells were harvested and ³Hincorporation measured. Inhibition of B cell proliferation correlateswith inhibition of BTK substrate phosphorylation after α-IgMstimulation. Importantly, a molecule with the same scaffold as I-7 butbiochemically inactive against BTK, I^(R)-7, is not active in the naïveB cell proliferation assay.

Example 261 Mass Spectrometry for TEC Kinase (Compound I-2)

TEC kinase (45 pmols; Invitrogen) was incubated with (I-2) (450 pmols)for 3 hrs at 10× excess prior to tryptic digestion. Iodoacetamide wasused as the alkylating agent after compound incubation. A control sample(45 pmols) was also prepared which did not have the addition of (I-2).For tryptic digests a 5 ul aliquot (7.5 pmols) was diluted with 15 ul of0.1% TFA prior to micro C18 Zip Tipping directly onto the MALDI targetusing alpha cyano-4-hydroxy cinnamic acid as the matrix (5 mg/ml in 0.1%TFA:Acetonitrile 50:50).

As depicted in FIG. 6, the expected peptide (GCLLNFLR) to be modifiedwas immediately evident after reaction with I-2 (MI mass of 359.17 Da)at MH+ of 1294.72. The peptide was also quite evident in the controlsample as modified by Iodacetamide at MH+ of 992.56. Interestingly theiodoacetamide modified peptide was not evident in the digest reactedwith compound I-2 indicating that the reaction was complete. There wasno evidence of other modified peptides.

Evidence of compound I-2 was observed at MH+ of 360.17 in the low massrange of the spectra. The fragmentation spectra of the 360.17 peak didshow diagnostic fragments that were apparent in the PSD spectra of themodified peptide at 1294.72 (See FIG. 6).

To further verify the presence of the modified peptides, both theiodoacetamide labeled (992.56) and I-2 labeled (1294.72) were subjectedto PSD (MS/MS) analsysis. After a database search of the NCBI nr Homosapien database using Mascot MS/MS Ion Search program the top match wasthe expected peptide in both cases.

Instrumental:

For tryptic digests the instrument was set in Reflectron mode with apulsed extraction setting of 2200. Calibration was done using the LaserBiolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20).For CID/PSD analysis the peptide was selected using cursors to set iongate timing and fragmentation occurred at a laser power about 20% higherand He was used as the collision gas for CID. Calibration for fragmentswas done using the P14R fragmentation calibration for the Curved fieldReflectron.

Example 262 Mass Spectrometry for TEC Kinase (Compound I-4)

TEC kinase (45 pmols; Invitrogen) was incubated with (I-4) (450 pmols)for 3 hrs at 10× excess prior to tryptic digestion. Iodoacetamide wasused as the alkylating agent after compound incubation. A control sample(45 pmols) was also prepared which did not have the addition of (I-4).For tryptic digests a 5 ul aliquot (7.5 pmols) was diluted with 15 ul of0.1% TFA prior to micro C18 Zip Tipping directly onto the MALDI targetusing alpha cyano-4-hydroxy cinnamic acid as the matrix (5 mg/ml in 0.1%TFA:Acetonitrile 50:50).

As depicted in FIG. 7, the expected peptide (GCLLNFLR) to be modifiedwas immediately evident at MH+ of 1355.72. This is the mass to beexpected when compound I-4, with an adduct mass of 420.21, is added tothe peptide mass of 935.51. The peptide was also quite evident in thecontrol sample as modified by Iodacetamide at MH⁺ of 992.56.Interestingly the iodoacetamide modified peptide was not evident in thedigest reacted with compound I-4 indicating that the reaction wascomplete. There was no evidence of other modified peptides.

Evidence of compound I-4 was observed at MH+ of 421.35 in the low massrange of the spectra. The fragmentation spectra of the 421.35 peak didreveal two prominent peaks that were apparent in the PSD spectra of themodified peptide at 1355.72 (See FIG. 7).

To further verify the presence of the modified peptide with compoundI-4, the peptide at MH+ of 1355.72 was subjected to PSD (MS/MS)analsysis. Because of the low intensity of fragments, a databasecorrelation was not possible. However, diagnostic fragments from the I-4molecule itself provided confidnece in the identification. Diagnosticfragments at MH+ of 376.38 and 421.83 are from I-4.

Instrumental:

For tryptic digests the instrument was set in Reflectron mode with apulsed extraction setting of 1800. Calibration was done using the LaserBiolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20).For CID/PSD analysis the peptide was selected using cursors to set iongate timing and fragmentation occurred at a laser power about 20% higherand He was used as the collision gas for CID. Calibration for fragmentswas done using the P14R fragmentation calibration for the Curved fieldReflectron.

Example 263 Mass Spectrometry for TEC Kinase (Compound I-7)

TEC kinase (45 pmols; Invitrogen) was incubated with (I-7) (450 pmols)for 3 hrs at 10× excess prior to tryptic digestion. Iodoacetamide wasused as the alkylating agent after compound incubation. A control sample(45 pmols) was also prepared which did not have the addition of (I-7).For tryptic digests a 5 ul aliquot (7.5 pmols) was diluted with 15 ul of0.1% TFA prior to micro C18 Zip Tipping directly onto the MALDI targetusing alpha cyano-4-hydroxy cinnamic acid as the matrix (5 mg/ml in 0.1%TFA:Acetonitrile 50:50).

As depicted in FIG. 8, the expected peptide (GCLLNFLR) to be modifiedwas immediately evident at MH+ of 1280.73. This is the mass to beexpected when compound I-7, with an adduct mass of 345.16, is added tothe peptide mass of 935.51. The peptide was also quite evident in thecontrol sample as modified by Iodacetamide at MH+ of 992.56.Interestingly the iodoacetamide modified peptide was not evident in thedigest reacted with compound I-7 indicating that the reaction wascomplete. There was no evidence of any other modified peptide at MH+ of1985.93 (TIDELVECEETFGR).

Evidence of compound I-7 was observed at MH+ of 346.32 in the low massrange of the spectra. The fragmentation spectra of the 346.32 peak didshow many diagnostic fragments that were apparent in the PSD spectra ofthe two modified peptides (See FIG. 8).

To further verify the presence of the modified peptides with compoundI-7, the peptides at MH+ of 1280.73 and 1985.93 were subjected to PSD(MS/MS) analsysis. A correlational analysis with the homosapien databaseidentified the correct peptide modified by I-7.

Amino acids 696 to 1022 of the EGFR-WT kinase domain (NM_(—)005228,NP_(—)005219.2) was subcloned into the NcoI and HindIII sites of thepFastHTa vector (Invitrogen, Carlsbad, Calif.). To make the EGFR-mutantprotein, the cysteine at position 797 was changed to a serine using theStratagene QuikChange kit (Stratagene, Cedar Creek, Tex.), according tomanufacturer's instructions.

(ii) Expression

P1 baculovirus stocks were generated in SF9 cells via Blue Sky Biotech'ssuspension transfection protocol (Worcester, Mass.). Expression analysiswas conducted in 125 ml culture of SF21 insect cells ((grown in SF900ISFM (Invitrogen cat #10902-088), supplemented with 10 mg/L gentamicin(Invitrogen, Carlsbad, Calif., cat#15710-064)) using a viral load of 0.1ml of virus per 100 ml of cell suspension. Expression was optimizedusing Blue Sky Biotech's Infection Kinetics Monitoring system(Worcester, Mass.).

(iii) Purification

Infected insect cells were pelleted. Cell pellets were resuspended inBlue Sky Biotech's lysis buffer (Worcester, Mass., 1×WX; solubilizationbuffer, containing a protease inhibitor cocktail of leupeptin,pepstatin, PMSF, aprotinin and EDTA) at a ratio of 10 ml per gram of wetcell paste. Cells were lysed by sonication and the lysate was clarifiedby centrifugation at 9,000 RPM for 30 minutes in a GSA rotor. 500 μl bedvolume of NiNTA resin (Qiagen, Valencia, Calif.) was added to thesupernatants and batch bound for two hours with constant agitation. Thematerial was transferred by gravity into an empty 2 ml column. Thecolumn was washed with 2 ml of wash buffer (Blue Sky Biotech, Worcester,Mass., 1×WX, 25 mM imidazole). The protein was eluted with1×WX+imidazole at varying concentrations: Elution 1: 75 mM imidazole (2fractions, 1 column volume); Elution 2: 150 mM imidazole (2 fractions, 1column volume); Elution 3: 300 mM imidazole (2 fractions, 1 columnvolume). All the elution fractions were analyzed by SDS page followed byCoomassie staining and Western Blotting using anti-penta-his antibody(Qiagen, Valencia, Calif.). The carboxy-terminal six-histidine “tag” wasremoved from some of the purified protein using AcTEV Protease kit(Invitrogen, Carlsbad, Calif., Cat#12575-015), following manufacturer'sinstructions. All the samples (pre- and post-Tev cut) were analyzed bySDS page followed by Coomassie staining and Western Blotting, asdescribed above.

One set of cells was then stimulated with 100 ng/ml EGF for 5 min,and extracts were made as described. The other set of cells was washedfree of compound I-7 with warmed compound-free medium, incubated for 2hr, washed again, incubated another 2 hr, washed again, and thenincubated another 2 hr washed again and incubated for additional 2 hrand then stimulated with EGF. The results of this experiment withcompound I-7 are depicted in FIG. 10.

Example 274 Washout Experiment in HCC827 Cells Containing EGFR DeletionMutantHCC827

Cells (ATCC, Manassas, Va.) were plated in Growth Media (RPMI 1640)supplemented with 10% FBS, 10 uM HEPES, 2 mM 1-glutamine, 1 mMNaPyruvate and pen/strep (Invitrogen, Carlsbad, Calif.) at a density of2.5×10⁵ cells per well in 6 well tissue culture plates. Twenty fourhours later the cells were washed 2× with PBS then serum starvedovernight in Basal Media (Growth Media without FBS).

The following morning the media was removed and 2 ml fresh Basal Mediacontaining 1 uM compound in 0.1% DMSO was added to duplicate wells. At 1hour, one well of cells was treated with 100 ng/ml of EGF for 5 minutes,rinsed with PBS, then lysed by scraping into 75 ul of Cell ExtractionBuffer (Invitrogen, Carlsbad, Calif.) plus PhosSTOP PhosphataseInhibitor and Complete Protease Inhibitor (Roche, Indianapolis, Ind.)for the Oh time point. The compound was removed from the second set ofwells and they were washed 2× with Basal Media. The cells were washedwith Basal Media every 2 hours until 8 hours when they were treated withEGF and lysed as at the 0 h time point.

Lysate protein concentrations were determined by BCA Assay (Pierce,Rockford, Ill.) and 10 ug of each lysate was separated by 4-12% gradientSDS-PAGE (Invitrogen), transferred to Immobilon-FL membrane (Millipore)and probed with rabbit anti-Phospho-EGFR (Tyr1068) (Zymed-nowInvitrogen) and mouse anti-EGFR (Cell Signaling Technologies, Danvers,Mass.) antibodies. Phospho-protein signals were quantitated usingOdyssey Infrared Imagning (Li-Cor Biosciences, Lincoln, Nebr.). Theresults of this experiment are depicted in FIG. 9 where it showscompound I-2 compared to results of compound I-4 and compound I-7 in thesame “washout” experiment.

Example 275 Mass Spectrometry for ERBB4

Erbb4 kinase domain (Upstate) was incubated with compound for 60 minutesat 10-fold excess of compound I-4 and I-11 to protein. 1 μl aliquots ofthe samples (total volume of 4.24 ul) were diluted with 10 μl of 0.1%TFA prior to micro C4 ZipTipping directly onto the MALDI target usingSinapinic acid as the desorption matrix (10 mg/ml in 0.1%TFA:Acetonitrile 50:50). For intact protein mass measurement theinstrument was set in Linear mode using a pulsed extraction setting of16,952 for the myoglobin standard used to calibrate the instrument(Shimadzu Axima TOF²).

Intact ErbB4 protein occurs at MH+ of 35850 with corresponding sinapinic(matrix) adducts occurring about 200 Da higher. A stoichiometricincorporation of the test compound (I-4 and I-11) (Mw of 410 Da)produced a new mass peak which is approximately 410 Da higher (MH+ of36260). This is consistent with covalent modification of ErbB4 withcompounds I-4 and I-11.

Example 276 ErbB1, ErbB2 and/or ErbB4 Kinase Inhibition

Compounds of the present invention were assayed as inhibitors of one ormore of ErbB1, ErbB2, and/or ErbB4 in a manner substantially similar tothe method described by Invitrogen Corp (Invitrogen Corporation, 1600Faraday Avenue, Carlsbad, Calif., CA;http://www.invitrogen.com/downloads/Z-LYTE_Brochure_(—)1205.pdf) usingthe Z′-LYTE™ biochemical assay procedure or similar biochemical assay.The Z′-LYTE™ biochemical assay employs a fluorescence-based,coupled-enzyme format and is based on the differential sensitivity ofphosphorylated and non-phosphorylated peptides to proteolytic cleavage.Using this assay, Compound I-56 was found to inhibit ERBB1 with an IC₅₀of 2,233 nM. Using this assay, Compound I-56 was found to inhibit ERBB4(HER4) with an IC₅₀ of 2,165 nM.

Example 277 Mass Spectrometry for Janus-3 Kinase (JAK3)

JAK3 kinase (33 pmols; Invitrogen) was incubated with (I-7) (327 pmols)for 3 hrs at 10× excess prior to tryptic digestion. Iodoacetamide wasused as the alkylating agent after compound incubation. For trypticdigests a 5 ul aliquot (5.5 pmols) was diluted with 15 ul of 0.1% TFAprior to micro C18 Zip Tipping directly onto the MALDI target usingalpha cyano-4-hydroxy cinnamic acid as the matrix (5 mg/ml in 0.1%TFA:Acetonitrile 50:50).

As depicted in FIG. 11, the expected peptide (LVMEYLPSG{umlaut over(C)}LR) to be modified was immediately evident as the largest peak atMH+ of 1725.88. This is the mass to be expected when compound I-7, withan adduct mass of 345.16, is added to the peptide mass of 1380.70.Interestingly the iodoacetamide modified peptide was not evident at MH+of 1437.73 in the digest reacted with compound I-7 indicating that thereaction was not entirely complete. There was also evidence for a numberof other modified peptides, however, their signals were low.

Evidence of compound I-7 was observed at MH+ of 346.12 in the low massrange of the spectra. The fragmentation spectra of the 346.12 peak didnot show diagnostic fragments that were apparent in the PSD spectra ofthe modified peptides (See FIG. 11).

To further verify the presence of the modified peptides with compoundI-7, the peptides at MH+ of 1725.88 and 1118.55 were subjected to PSD(MS/MS) analsysis. A correlational analysis with the homosapien databaseidentified the correct peptides as being modified by I-7. Compound I-11was also tested using the same procedure and showed measurablemodification.

Instrumental:

For tryptic digests the instrument was set in Reflectron mode with apulsed extraction setting of 2200. Calibration was done using the LaserBiolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20).For CID/PSD analysis the peptide was selected using cursors to set iongate timing and fragmentation occurred at a laser power about 20% higherand He was used as the collision gas for CID. Calibration for fragmentswas done using the P14R fragmentation calibration for the Curved fieldReflectron.

Example 281 BTK Occupancy in Ramos Cells with I-7 and I-215 UsingStreptavidin Beads

Ramos cells were incubated with 0.1, 0.05, 0.01, or 0.001 μM I-7 inserum free media for 1 hour at 37° C. The cells were pelleted bycentrifugation and lysed in Cell Extraction buffer (Invitrogen) for 10minutes on ice, centrifuged (10 minutes at 14,000 rpm) and thesupernatant was collected. Cell lysates were incubated with 1 μM I-215for 1 hour at room temperature, then incubated with streptavidin-coupledagarose beads (ThermoFisher) overnight at 4° C. The beads were washedthree times with lysis buffer and the bound proteins were boiled off thebeads at 95° C. for 5 minutes in 4×LDS Sample Buffer. The amount of BTKassociated with the probe I-215 was assessed by BTK western blot. Allvalues were normalized to the DMSO-treated sample which is set to 100%.FIG. 16 shows the western blot; FIG. 17 shows quantitation of FIG. 16demonstrating unoccupied BTK protein is available to the probe I-215when the cells have been exposed to low concentrations (10 nM, 1 nM) ofI-7 but at higher concentrations of I-7 the BTK protein is fullyoccupied and cannot interact with I-215.

Example 282 Washout Experiment with I-7 and Probe Compound I-215

Ramos cells were incubated with 0.1 μM I-7 or a reversible BTK inhibitorcontrol compound in serum free media for 1 hour at 37° C. The cells werethen washed in compound-free media and lysed 0, 4, 6, or 8 hours aftercompound removal. Cell lysates were incubated with 1 μM I-215 for 1 hourat room temperature, then overnight at 4° C. with streptavidin-coupledagarose beads. Protein was boiled off the beads and BTK association wasassessed by western blot. FIG. 18 shows the Western blot; FIG. 19 showsthe quantitation of FIG. 18 and demonstrates all the BTK protein remainsoccupied by I-7 for over 8 hours. This suggests that the timeframe forre-synthesis of detectable BTK protein in Ramos cells is greater than 8hours. In contrast, with the reversible inhibitor control, 45% of BTKprotein is unbound and available to the probe at 0 hours and by 4 hours100% of BTK protein is unbound and available to bind the probe. Allsamples were normalized to the DMSO-treated cells harvested at 0 hours.

Example 283 Measuring BTK Occupancy from In Vitro Samples by ELISA

In order to determine the amount of free BTK in cell or tissue lysates,an ELISA protocol was employed that utilizes a biotinylated probecompound that binds only to free, unoccupied BTK. The conjugated biotinis captured on a streptavidin-coated ELISA plate and detected with amouse anti-BTK antibody (Becton Dickinson, Franklin Lakes, N.J., USA)and a secondary goat anti-mouse HRP antibody (Zymed, South SanFrancisco, Calif., USA).

All samples were prepared with equal concentrations of Biorad lysisbuffer (Hercules, Calif., USA), 0.5% bovine serum albumin in PBS with0.05% Tween-20 to give a final concentration of 1 μM I-215. Samples wereincubated in a mixing plate for 1 hr at room temperature while shakingto allow probe compound I-215 to bind to free BTK. After incubation withI-215, samples were added to a washed, streptavidin-coated ELISA plate(Pierce, Rockford, Ill., USA) and incubated for 1 hr at room temperaturewhile shaking. The plate was then washed with PBS containing 0.05%Tween-20 using an automatic plate washer. Anti-BTK antibody was preparedat 1:1000 dilution in 0.5% BSA in PBS (0.05% Tween-20) and added to theELISA plate. The plate was incubated for 1 hr at room temperature whileshaking. The plate was washed as described above and the secondary HRPantibody was prepared at 1:5000 dilution in 0.5% BSA in PBS (0.05%Tween-20). The plate was incubated and washed as described above. TMBwas added to the plate, and OD₆₅₀ was monitored until reaching 1 ODunit. The reaction was then stopped with addition of H₂SO₄. The platewas analyzed using Gen 5 software, and a 4 Parameter Logistic curve wasemployed to quantitate samples. Recombinant BTK (Invitrogen, Carlsbad,Calif., USA) was used for the standard curve.

Table 19 shows results with Ramos cells reported as concentration atwhich >50% or >90% of BTK is occupied. A concentration designated as “A”is greater than 1 nM; a concentration designated as “B” is greater than10 nM; and a concentration designated as “C” is greater than 50 nM.

Example 286 Proteomics Analysis

Proteins that are covalently bound to I-215 in a cell lysate areidentified using mass spectrometry. Cell lysate is incubated with 1 μMI-215 for 1 hour at room temperature, followed by the addition ofstreptavidin-coupled agarose beads. Mass spectrometry is used toidentify proteins other than BTK. These are potential “off-target”interactions.
